Reading / Setting the Scale Factor
Note: Not available in mode 0 and 0 +128
Syntax:
S <CNo.> [ = SC, W1, W2, DP ]
S command
<CNo.> channel number 0
= optional to set scale factor, otherwise read
SC scale (here always 0)
W1 display value at measured value 0 (integer)
W2 display value at measuring range limit value 20000 (integer)
DP number of decimal positions (0 - 4)
To calibrate the electrical size to the actually measured physical size, a 2-point scaling is car-
ried out. To do this, both measuring points, zero value and limit value, are assigned to the
display values. The display value is given as digit without decimal point; the decimal posi-
tions are given separately.
Example: Scaling to 0 mA (0
µ
A) = 0
20 mA (20000
µ
A) = 160.00
Computer: S0=0.0.16000.2
Instrument: OK
Read scale factor
Computer: S0
Instrument: 0. +0.+16000.2
Note: As the scale factor at measurement outputs with linearization, e.g. temperature
measurement, is based on internal table values, changing of the scale factor is useless.
In the operating mode <128 the setting of the scale factor is locked (see section Rea-
ding/Setting the Operating Mode)
